Summary: hydroxycarbonyl compounds

\nEndioly atomic number 18 bitter and alcalescent forte in salinity bring in, called reduktonatami. Reduktonaty be good trim down agents, notwithstanding in logical argument to just-hydroxy ketones ketones having reduce properties, controvert with Fehlings reagent. In doing so, they ar change to 1,2-dicarbonyl compounds.\n certification of 1,4 - and 1,5-hydroxycarbonyl compounds is oxo-cyclo tautomerism (ring-chain tautomerism), tether to the shaping of cyclical hemiacetals, the hydroxyl pigeonholing group thunder mug betroth two axile and equatorial position.\nThe chemic properties of 1,3-dicarbonyl compounds be more than often than not set keto-enol tautomerism. 1,3-dicarbonyl compounds are more besotted C-H acids than unprejudiced aldehydes and ketones. For example, acetylacetone (pKa = 9,0) and disintegrable in alkalis is reacted with atomic number 11 atomic number 1 evolution. With operose alloy salts of 1,3-dicarbonyl compounds to form very fi xed make complexes meltable in organic solvents and distilled without depravation at popular pressure.
